The savvies were mixed using a food blender. The customer stated that when Attasorb RVMwas tried that separation was evident. We did not rind any separation occuring iHth any of the samples. In fact, the samples prepared with the Attepulgites seemed to be more hoajeganeous than that prepared with the asbestos. On the other hand, the bulk volu&e seemed to decrease in the order of asbestos, Attsorb, Attaelay, and Att&cley X-250, ` Perhaps, If the blender operation wore improved by the customer, a more hoiogenoouc separation would oceor. \ 4 ^ggg Dale Ccmpt6led_3 / / ? ; / V f Houri._.4 L Notcbeok Re }?> f Signed!_ PADUANO CONFIDENTIAL PVTflij i^fFiFK BAS
